一种混凝土表面用环氧弹性腻子
摘要：
本发明涉及一种混凝土表面用环氧弹性腻子，由A组分和B组分构成，A组分由重量百分比计的下述组分构成：液态环氧树脂5～20％，柔性环氧树脂5～20％，锐钛型钛白粉3～10％，滑石粉10～30％，重质碳酸钙30～60％，混合稀释剂5～15％；B组分由重量百分比计的下述组分构成：聚酰胺树脂10～20％，聚醚改性胺10～25％，重质碳酸钙40～60％，滑石粉15～35％，混合稀释剂5～15％，防流挂剂0.5～2％，A组分和B组分的质量比为10:3～4。本发明环氧弹性腻子综合了环氧腻子和纯丙乳液弹性腻子的优点，与混凝土基材附着力优异，较好的可绕性和韧性，在高低温环境中有良好的抗开裂性。
摘要（英）：

The invention relates to epoxy elastic putty for the surface of concrete. The epoxy elastic putty is composed of a componend a component B; the component A is prepared from the following ingredients in percentage by weight: 5-20% of liquid epoxy resin, 5-20% of flexible epoxy resin, 3-10% of anatase titanium dioxide, 10-30% of talcum powder, 30-60% of heavy calcium carbonate, and 5-15% of a mixed thinner; the component B is prepared from the following ingredients in percentage by weight: 10-20% of polyamide resin, 10-25% of polyether modified amine, 40-60% of heavy calcium carbonate, 15-35% of talcum powder, 5-15% of a mixed thinner and 0.5-2% of an anti-sagging agent, and the mass ratio of the component A and the component B is 10 to (3-4). According to the epoxy elastic putty, the advantages of epoxy putty and pure acrylic emulsion elastic putty are combined, the epoxy elastic putty has excellent adhesive force with a concrete base material, has good reelability and toughness, and has the good anti-crack property in a high-low temperature environment.
